The Warrego Highway is located in southern Queensland, Australia. It connects coastal centres to the south western areas of the state, and is approximately 715 km in length. It takes its name from the Warrego River, which is the endpoint of the highway. The entire highway is part of the National Highway system linking Darwin and Brisbane: formerly National Highway 54, Queensland began to convert to the alphanumeric system much of Australia had adopted in the early-2000s and this road is now designated as National Highway A2.

State-controlled road

edit

Warrego Highway is a state-controlled road, divided into seven sections for administrative and funding purposes. Six of the seven sections (numbers 18A to 18F) are part of the National Highway, while section 18G is a regional road.[1][2][3][4] The sections are:

  • 18A – Ipswich to Toowoomba
  • 18B – Toowoomba to Dalby
  • 18C – Dalby to Miles
  • 18D – Miles to Roma
  • 18E – Roma to Mitchell
  • 18F – Mitchell to Morven
  • 18G – Morven to Charleville

State-controlled roads that intersect with the highway are listed in the main article.

Route description

edit

The highway commences at the end of the M2 Ipswich Motorway, near Ipswich and runs to Helidon Spa, at the foot of the Great Dividing Range. From there it follows the Toowoomba Bypass to Charlton, west of Toowoomba. The Warrego then crosses the Darling Downs, bypassing the town of Oakey and then passing through the towns of Dalby, Chinchilla and Miles, in the Western Downs. The highway continues through the towns of Roma and Mitchell in the Maranoa Region of South West Queensland. After Morven, the A2 Route continues north–west along the Landsborough Highway, with the western turnoff continuing the Warrego Highway down to its terminus at Charleville.

The section of highway between Ipswich and Charlton is mostly motorway grade; a four lane divided highway with motorway-style on-ramps and off-ramps. At a point between Charlton and Oakey the highway merges from 4 to 2 lanes (however, throughout 2017–2019, the highway was planned to be duplicated up until Oakey)[5] Then, the highway mostly continues in a straight line with minimal turns. At Dalby, the highway briefly returns to 4 lanes (where a longer stretch of the highway was planned to be duplicated in 2017). The Warrego then continues as a rural 2 lane highway, until Charleville.

Terrain

edit

The Warrego Highway's lowest point along its length is 3.69 m just east of where it crosses the Bremer River near Ipswich, and its highest elevation is at the top of the Great Dividing Range on the Toowoomba Bypass.[6]

History

edit

In January 2011, the former highway was extensively damaged where it crossed the Toowoomba Range. This included land slips, shoulder and embankment erosion, the erosion of drains and damaged rock fall netting.[7] The road wasn't fully repaired with all four lanes open until September 2011.[8]

The Toowoomba Bypass was completed in September 2019 and bypasses the urban area of Toowoomba and provides a better crossing of the Great Dividing Range. Warrego Highway (A2) was rerouted via the bypass between Helidon Spa (in the east) and the interchange at Charlton (in the west). The bypass continues as the Gore Highway (A39) and is 41 km in length. The original section of Warrego Highway through Toowoomba was renamed Toowoomba Connection Road (A21).[9]

Major works

edit
  • 1957 – Helidon bypass. New road built to bypass Helidon including a steel and concrete bridge over Lockyer Creek opened by the end of June 1957.
  • 1959 – Ipswich bypass. New 8 mile long bypass including a steel and concrete bridge over the Bremer River built to bypass Ipswich City, shortening the highway by 2 miles. Also completed this year was the first bridge over Laidley Creek at Crowley Vale.[10]
  • 1966 - Lockyer Creek bridge. On a new alignment between Robinson's Bridge and Grantham, construction of a steel and concrete bridge 370 ft long over Lockyer Creek was completed and a 3.6 mile section of road bypassing a series of curves between Grantham and Gatton was opened to traffic.[11]
  • 1968 - The final 16 mile section of highway between Morven and Charleville was sealed. Work was completed late in the year.[12]
  • 1970 - Construction of a four-lane section, 1.7 miles in length, from Withcott to join with the four-lane section on the Toowoomba Range was completed.[13]

Darren Lockyer Way

edit
 
"Welcome to Darren Lockyer Way" signage at Ipswich end of Warrego Highway heading westbound.

On 28 September 2011 the Queensland Main Roads Minister, Craig Wallace, announced that an 85 km stretch of the Warrego Highway was to be renamed Darren Lockyer Way, in honour of the retired Brisbane Broncos, Queensland and Australian rugby league captain. The section of road renamed is from Riverview to the bottom of the Toowoomba Range at Withcott. Special signage including "Welcome to Darren Lockyer Way" has been erected.[29]
